RWD Conversion Complete...one word...AWESOME!!!

Or...you could leave it AWD and enjoy it that way as well.

I think the rear suspension is the same, so the GT2 coilover should be straight bolt on.
The front is a little challenging with new carrier and all kinds of stuff.
But what I really want to know is the GT2 harness and DME, that would be doing it right, no?

This is the only way that I konw to get rid of it properly.
Ruf won't reprogram the Turbo DEM (tried already).
Or if you have another way, I am all ears.

When I turn my PSM off (which I do 98% of the time), it's off completely.

Maybe then I can generate the Testicular fortitude to make the conversion.

PSM comes back on when you really trail brake because it thinks you need help. Have you tried it on the track?
You need to do yourself a favor and not tell others what is good for them. The GT2 does everything I wanted. It lets me do lurid oversteer on the street, and it lets me trail brake all day long without that stupid PSM coming back on trying to save me form myself.
Like what Turbo's used to be, made famous by the 964 Turbo, the Widow Maker.

When I did the conversion I only removed the torque tube, I wanted to try it out before doing the whole conversion, what Scott fails to mention is that me not liking the RWD had nothing to do with handling because the car handled better in RWD, though it overpowered the wheels, which LSD would certainly have helped, to me if you are going to do all that then just get a GT2.
But my problem was that my car didnt pull the same way out of corners, on the highway from 20 to 100 or 60 to 130, just wasnt the same in a straight line, and it had nothing to do with LSD or front drivetrain friction. The car was just slower accelerating. Car did still understeer though which woud be made to greater affect by taking more weight from the front of the car unless you completely change the front end to GT2 spec, at which point you have done : LSD, Complete RWD conversion, Front suspension configuration, and you still dont have a GT2 because you still have motor mounts, about 400 lbs, PSM to disable, clutch actuators to remove and several other things to change, and it's still likely you will be off and at this point you have more than covered the extra cost of getting a GT2 so just get the GT2.
I have said before and I will always say the turbo is not meant to be RWD unless you drive in straight lines only, which a Porsche was never meant to do.

My observations on PSM.....
It has been bothering me and my tuner for some time now that PSM is acting up at the 1/4 track.... and after the recent 1/4 day we concluded that the car is being held back by PSM. Even Todd K thought it was on the dyno.... Cels coming on and pulling back the car. Now this was at 800 rwhp etc...
My car is slightly different though since Im running GT3 code and not the 996TT code in my car. But the PSM code is identical to that of a 996TT.
Too bad we didnt run the car with PSM disabled all together.... I think we would get some better numbers... next time....

JOe, I know its hard to understand... I even let two other guys drive my car one of which is not a even a P car owner except he is a Evo tuner and he said the saem thing today after he drove it. So we ran the car without the PSM stuff by pulling the fuse and the car came alive... maybe u should try it... no joke. Just don't slam on the brakes too hard...
I had the option of having it disabled altogether via ECU but I would have to sacrifice ABS as well.
Yes we can do burnouts but it is still passive active.... it even says so in the manual. God only knows what its doing at that HP level.
Heavychevy,
It can be done by running GT2 code... u still maintain ABS that way but do not have PSM. However, Im not sure that would work with AWD.
Problem is that PSM and ABS go hand in hand in the 996 TT code...

Im going to run some datalogs via the PBox back to back with and with the fuse soon and ILL compare the data... but we are pretty sure its holding it back.... Even my tuner believes so....
Now, Im at a lot more HP so That may have something to do with this as well. The trick, and I heard some have done this, is to run GT2 code on a RWD 996 TT... u maintain ABS but no PSM...

Confused and Undecided
OK...with all being discussed.
Is the 996TT a faster, better steering & handling car with the conversion than the AWD version?
I am not a drag racer, I personally am looking to reduce weight,
improve steering response and handling. And ultimately make an overall
quicker better car.
Is the improvements only a matter of preference and opinion?
Or does the conversion actually improve the car towards the GT2 standard?
